反求工程中曲面生成算法的研究

Research on the surface forming algorithm in reverse engineering

介绍了曲面造型技术的发展过程和反求工程的概念、应用及关键技术,在深入分析和比较各种曲面造型方法的基础上,阐明了NURBS方法是反求工程中曲面生成的最优算法,并用NURBS方法对某车体覆盖件进行了曲面重构.

This article points out the development process of surface modeling technique,and presents the concept,the application and the key technology of Reverse Engineering. According to this article, all kinds of surface modeling technique applied in Reverse Engineering is deeply analyzed and compared,on the basis of which it explains that NURBS method is the best algorithm in RE. Using NURBS method,this paper reconstructs a cover part of a vehicle.
